Designing of a production ordering system for automobile repair parts

This paper aims to design a production ordering system for automobile repair parts which satisfies users' demand with low inventory. We analyze the characteristics of a time-series demand structure of automobile repair parts and propose a production ordering system for those parts which are supplied to overseas markets in the form of a mathematical model based on the concept of a pull-type ordering system. We also analyze the effects of transportation lead time on the variation of production and transportation ordering quantities and inventory quantity, and propose a way for designing of an economic buffer stock level at each stock point.
